The rapid evolution of Large Language Models has shifted the paradigm from simple text completion to complex, agentic workflows. In this new paradigm, AI agents are assigned persistent identities and multi-step tasks (e.g., "You are Vivian Taylor, a research assistant; compile a report on marine biology").
